There was a problem hiding this comment.
This has had a lot of discussion and several implementations with no complaints

…-telemetry#4768) ## Changes Adds the merge algorithm specified in OTEP#264 to the Resource + Entity data model specification (both still in development). This merge algorithm has been used in Entity prototypes for the past year and has not seen any change. It's been adaptable enough to handle several re-architectures of SDKs through prototyping, so we're confident in pushing it forward into the specification. A few caveats: - See the note on Resource DataModel about conflicting merge algorithms. This one currently focused only on merging entities into resource when there is a known set of entities in the existing resource. - I've split the merge algorithm into two: The Entity portion about eligibility of merging and descriptive attribute merging, and then the more robust resource section.
